Methods and apparatus for processing voice call requests based on communication conditions of a mobile communication device are disclosed. In one illustrative example, a voice call request for a voice call is received through a user interface during an out-of-coverage condition of the mobile device. In response to the voice call request, when the out-of-coverage condition has existed for an out-of-coverage time period that is less than a first time period, a scanning operation is performed during a delay time period. If the out-of-coverage condition still exists upon expiration of the delay time period, a call denial indication and a call reminder prompt are produced in a visual display which indicates that the voice call could not be completed. If an in-coverage condition with a wireless network is identified during the delay time period, however, a voice call associated with the voice call request is initiated via the wireless network. On the other hand, in response to the voice call request when the out-of-coverage condition has existed for an out-of-coverage time period that is greater than the first time period, the call denial indication is immediately produced in the visual display without delaying for the delay time period.
